EUGENE L. BARNES, OF BUFFALQ, NEVJ YORK, AEv'SIGNOR TO AIiEERICAll' DISTRICT SIEAIE COZ IPANY, 0F NORTH TOZ-IA'WTANDA, NEW YORK, A'CORPOEATION OF NEW YORK.

To all "uh/mm mcg conccrr lie it known that i, l. GENE L. Barnes, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New fork, have invented certain new and useful improvements in Liquidlifieasuring Structures, of which the following is a specification, reference being had therein to the accoiupanyin drawing. n

This inve n relates primzi rily to liquid measuringstructures andhas more particular reference to devices 'i'or metering water of condensation and other similar fluids.

The primary object ot the invention is to privide a liquid measuring;- and metering structure which certain in its operation, accurate in the results which it produces, and practically free from disturbance by reason of extraneous conditions whereby its operation would be seriously atliected.

Another object ot' the invention is to provide, in such a structure, means whereby the metering' operation is effected in a practically continuous manner and in accordance with the flow of t e liquid being measured.

i k still further object within the contemplation of the invention is to provide for ready access to the internal pari'zs of the structure by an oper tor and yet be so constructed that it maynot be tampered with by a user; and, to this end the structure ncludes a casing ct separable sections izih means for securely fastening them together.

iiiiti another object of the invention, and

one of considerable importance, is to rovide means tor cleanin the fluid-operated drum forming component of the structure.

l ith these and oth r objects in view, the invention resides in a novel construction, in a unique aggroupment otits compmients,

d in certain details thereof, all as hereina'l'ter set forth.

in the particulars tuation in which my improved metering; structure is to be utilized, it isn't 0 'nc importance that the amount of fluid through the structure shall he metereo with the highest degree of exactus in other words, where my measuring device is employed for metering water of condensation resulting from steam supplied to. a user from central plant, there should no. factor of uncertainty in the quantity be of the fluid developed inasmuch as the user Application filed December 31, 1918. Serial No. 343,607.

is charged, for the steam supplied, on the basis of the amount of the water of condensation which results from the used steam. It has now come to be a very general practice to generate steam at a central plant and, then, to supply it to various users in a community, to buildings, apartment houses, residences, etc, and in connection therewith, various types of measuring instrumentalities have been developed and used; but, by reason of more or less unsatisfactory results incident thereto, the present invention was (level i and this, in practice, has been iiount to be not only satisfactory but, from evil point of view, successful, in that it includes relatively few parts, is exact and certain in the results produceihand is readily installed anchthereatter, inspected and maintained in workable condition.

in order that the invention may be more readily comprehended, I have disclosed the same in the accompanying" drawings; but it to be understood that these are, for the most part I srely illustrative and consti tut-c a preferred and practical embodiment r the invention; and, in thus showing' one embodiment, it is to be recognized that my inventive concept is susceptible of other embodiments and utilizations with a wide range or modification and variation, without departing from the spirit of the invention or sacrincingi; any it its salient or underlying principles.

in these drawings:

Fig. l is a view in central vertical section of a liquidmeasuring structure made in ac- 1 ance with my invention partly in vertical trans- 2 is view ction, on'the line 2F2, Fig. 1, of

r: s a detached view, in elevation, of

i is frag; sentary view, insection, of one ofthe closure devices disposed in one wall of the drum;

6, T, 8 and 9 are views of the liquidoperated drum, detached, showing the same in its, successive positions as actuated by the inflowing of the liquid and the discharge ofsuch liquid from the central compartment into each of the liquid-receiving compartments and also illustrating how the lips or baffles at the discharging portions of the rotor insure the filling of one of the receiving-compartments before filling of another compartment is initiated;

- component 2 and a lower component 3; these two components being combined to form an internal chamber a in which a rotatable drum or rotor 5 is housed.

The lower component 3 is provided with dlscharge-ports or openings 6, formed preferably n itslower portion and opening'into La liquidmeceiving chamber '7, this chamber being adapted to have delivered toit, dur- I preferably and as shown, l.-sha 1ed.

, similarly the engaging portions of the bolting' the rotation of the drum, the liquid-contents of the drum which actuate the latter. The upper and lower-components 2 and 3 of the casing are, preferably and as shown,

locked together in a manner that eliminates the employment of. bolts along a flanged edge or periphery: To this end, the joint 8 between the upper and lower components is,

over, each component, contiguous to the joint and at one side thereof, is formed with a half-section 9 and 10, respectively, of a boss. These bosssections are provided with a tapered surface 9 and 1.0 respectively," adapted to be embraced by a tapered nut-and-bolt element 11, this bolt being threaded into one end of a shaft 12 upon which thedrum 5 is mounted and which constitutes the axis of its ro'tative movement. Theboss-sections 9 and 10 form a journal for one end of the shaft 12. The opposite end of this shaft is similarly journ'aled in tapered boss-sections 13 and 14 formed on the opposite side of the upper and lower casing-components. The shaft 12 is formed with an enlarged head 15 adapted to embrace the bossseotions 13 and 14:. By reason of the fact that the surfaces of the bosssections 9, 10, 13 and 14 are tapered, and

lland the head 15, the screwing of the bolt 11 into the shaft 12 has a tendency to draw these two elements together with a consequent tendency to tighten the L-shaped joint 8 between the upper and lower halves of the casing. By this means, the cas halves or components are securely held Moregether and, in a sense, are locked against beingtampered with by a user; this locking means being, however, actuatable by a properly constituted wrench or other tool in the hands of an inspector, so as to afford the separation of the two casing halves and access,thus, to the interior of the casing.

The shaft 12 is, preferably and as shown, privided with a bore 16, centrally formed, and constitutes an intakenozzle which I will designate 17, the head 15 being internally threaded to provide a proper connection with a pipe leading to a service main or other source of. supply (not shown).

It will now be perceived that the nozzle 17 not only constitutes a means for introducing liquid from a source of supply into the casing but, also, constitutes the axis of rotation of the drum or rotor 5. I In order to facilitate the rotative movement of the drum on the nozzle, bearings 19 are interposed between the drum 5 and the shaft 12.

The rotor or drum 5 is adapted to be ro tated in a practically continuous'manner as the liquid flows through the nozzle'into the drum; and, by such rotative movement, is adapted to actuate a register, marked 20, disposed in this instance in the upper part of the casing component 2. Inasmuch as this register, in its details, and its particular location on the casing constitute no part of the present invention, I deem it unnecessary to describe it in detail beyond saying that it includes a dial 21 underlying a lid or cover 22 hinged to the upper section of a registerhousing 28 secured in the casing component 2, as shown. A pointer 24 is associated with the dial 21 and receives its motion through a tram of worm and gear elements marked,

generally,25, which, in turn, are actuatedby a star-wheel26 depending from the register housing 23 and occupying a position above the drum 5, but in a position to be ac tuated, from time to time, by a trip 27 projecting beyond the peripheral-outline of the drum 5 As the drum 5 completes a revolution the trip 27 is brought into operating engagement with the starwheel 26 and effects a partial rotation thereof and, thereby, the pointer 24 is moved one increment over the dial, the latterbeing provided with suitable metering dimensions, as well understood.

The flow of liquid through the nozzle 16 into the drum 5 may, under some conditions, be continuous, while, under other conditions, it is intermittent; but, however this may be, the operation of the register is rendered certain and accurate and the results thereon shown would be a true indication of. the exact quantity of fluid passing through this meter.

In order to secure the required certainty and accuracy of operation and results,ijust mentioned, it is a desideratum of my inventive concept that the drum 5 shall be so con- Ill) compartment 28, essentially of polyangularform so as to provide walls 29 necessarily arranged angularly to each other.

The central triangular compartment 28 is provided with discharging ports or openings 30. Contiguous to these ports and preferably formed as an extension of the walls 29 are liquid-guiding lips or baffles 32 which, preferably and as shown, are curved so as to provide a liquid-guiding surface which is approximately concentric with the axis of the drum. The walls of this compartment form, in cross-section, an approximately equilateral triangle, the axis of the drum being the mathematical central axis of the triangle, and the discharge ports being disposed in proximity to each apex.

As a means of communication between the bore 16 of the nozzle 17 .and the triangular compartment 28, the shaft 12 is provided with a port or opening 33. and this provides for the introduction of liquid, passing through the nozzle, into the triangular compartment.

.Concentrically arranged about the triangular compartment, and interconnected therewith, are a seriesin this instance there being three-of liquid-receiving compartments 34, 35 and 36, respectively. These outer liquid-receiving compartments are formed, in part, by the angular walls 29 of the polyangular compartment 28 and, also, by two angular walls 37, 38 and 39, respectively. Each two of these angular walls (37'38, 3839, and 39 37) form the end walls of the respective compartments. These compartments are also formed of an archshaped peripheral wall 450, l1 and 42, respectively. Thus, it will be seen that the outer compartment 34 comprises the angular wall 29 of the polyangula-r compartment 28, the two angula-rly-disposed end walls 37-38,and the peripheral wall 40, and the other compartments are similarly constituted. Preferably and as shown. the angular end walls (3738. 38-39, and 39 37) of the outer compartment extend on lines which are a-n gularly disposed to a line that would intersect the axis of rotation of the drum, and are, thus, somewhat angularly disposed in relation to the walls of the central compartment 28. The lips 32 are disposed between the end walls of the outer compartmentsand the walls of the central compartment 28, they extend into the outer compartments, as shown, and they 'proieet in adirection practicallyat right angles to the end walls of the compartments.

The several outer liquid-receiving co1n- 'partments are provided with elongated liquid-discharging channels 43, 44 and 415, these being peripherally disposed along the outer curved walls of the adjacent compartment, and are of predetermined dimensions, as to length and depth, so as to permit a definable quantity of liquid to accumulate therein preliminary to being discharged therefrom as the drum rotates.

Inasmuch as the action of the drum may, under some conditions-as by the internal pressure of the fluid pssing therethrough be somewhat affected, I may provide each of these liquid-discharging channels with a baffle or dam 5*, as shown in Fig. 11, the

function of which is to dam and retard the outflowing liquid and prevent it from effecting a sort of reaction on, the liquid then in the chamber 7 and, also, to effect a retarding action on the rotor and thereby prevent undue spinning thereof.

Operation: The operation of the structure, described in the foregoing, will be more or less self-evident: Assuming that it is entirely empty and that the compartment 34- occupies a filling position, namely, that shown in Fig. 1, the fiuidsuch as water of condensationwill pass from the nozzle through the port 33 therein andv into the central tank or compartment 28. From there, it'fiows toward the left (as shown in Fig. 6), through the left-hand port 30 and into thecompartment \Vhen this latter compartment is completely filled, and no more of the fluid can pass from the com- 'partment 28 into the compartment 34L, it will then begin to overflow the lip 32 at the right and into the compartment 35. Inasmuch as the drum will rotate in accord ance with the accumulation of weight of the fluid in the measuring compartment 28, the drum at all times, as the weight of the fluid effects an overbalancing action of the-drum, is given a rotative movement; but this will. not occur until the first filling-compartment 34: has been filled to its capacity, whereupon the fluid will rise against thebottom of the triangular compartment to a height where it will overflow the lip or dam 32 at the entrance of the next succeeding compartment, whereupon the accumulated weight of the fluid will cause the drum to rotate and, in its rotation, the opening of the preceding compartment will rise beyond the level of the water in the central compartment, thus accurately measuring the fluid in the preceding compartment before it is allowed, to discharge through the channel 43 into thechaimber 7. The fluid in this preceding compartn'ient 'will discharge in proportion to the accumulating fluid in the preceding compartment; but,at no time from the mo- 'ment iteommen es. to. discharge. can any additional fluid enter this compartment because the opening from the central com )artment will then be much higher than. thezontal position and gradually move from that position "as the Water fills, the. un-

. de'rlying compartment and overflows into the qcentral compartment and from that compartmentinto the next succeeding compartment, the gradual filling lot which effects a rctative movement ofthe drum and. flow of the Water into the channel 43.

This, then, is, itself, filled with the fluid.

and permits an overflowing o"? the same into the chamber 7. As illustrated, more or less diagrammatically, in Figs. 6', 7, 8 and 9, the emptying of the first compartment-say, compartment 8 lwill begin before the next succeeding conniartment for instance) is quite half full of the fluid. Eventually, compartment 35 reaches the position that had been occupiedby compartment 34-, the latter all the time discharging its contents into the chamber-7. As compartment 34;

I empties its contents and compartment 35 is being, filled, compartment 86 is, being brought into'the position first occupiedby compartment 35 and eventually Will reach filling; position, the same as compartment 35 had. And so on, successively, the different compartments are filled and emptied;

and this filling and emptyin operation continues the rotation of the drum so as to bring}; the trip 27 into engagementwith the SiRT-WhQGl 2G to operate the register.

A teatureot' importance in this construction is to admit the fiuid'into a compartment at a point not too remote from the periphery of the drum, and thereby-- effect a quick. and positive cut-off ofthe fluid when the drum rotates and the fluid rises above the water level in the central com partmentand begins to overflow into the next succeeding compartment. In this connection, the angular arrangement of the Walls of the central compartniient, as may readily be perceived, contributes to an important degree in first discharging its contents into the underlying compartment, (then being filled.) and, then, when that compartmentis, filled. and in predetermined relation to the rotation of the drum,'the fluid rises above the lowermost angular Wall of the central compartment, the tendency of the fiuid therein to flow intothe next succeeding compartment being at tirstfretarded by the battle or dam 82. As the fluid reaches a level indicatedby the line A-',A (Fig; 7), the discharge of thetluid from the compartment 28 into the l'compartment Set will cease and the fluid Will then beginv to'tlow into thec-ompartme-nt 55; thereupon, as the drum rotate s,the fluid will reach a level in compartments 28, 34; and35 indicated by line .B B (Fig. 8) and it is then thatthe fluid begins to discharge from, the

channel t3;'a'nd so on for each successive compartment. i

As indicated in- Fig. 10, the lines along Walls .37, 38 and 39 otthe outer comp-art ments hear an angular relation to. a line X- tending through the axis of the drum; and

this arrangement is important in controlling the instant of cutitng-oli of the flow otthe iluid froni the central compartment 28 into one compartment, and its overflow from the and a series of outer or filling compartments; but .in all. ofthose; instances with which I am familiar, thecentral compartment is cylindrical and the end alls of the outer compartments extend upon radial lines which intersect the axis of the drum.

In such an arrangement, the outflow of fluid first from the central eompartmentintoeach. successive outer compartment, and, then,

"from these vouter ctmipartmentsinto the receiving; chamber Tcannot, asl'have determined by experiments, be as effectually,

rapidly, andcempletelv accomplished as in the arrangement herein disclosed, l believe myself to be the first toprovide a sort tral compartment of triangular form,'.provided With a plurality otports at the cor.- ners of tliecentral compartment, such that, just as the fluid begins todischarge from the central. compartment into the next succeeding compartment, its flow into the p re ceding compartn'lent is instantly cut oil,

whereby only a predetermined quantity. of

ater can enter each filling compartment. from, the central compartment, with a consequent exactness in the operative rotation of the drum to show its result with precise ness on the register associated with, the drum.v M

By reason, of the accumulation of sediment, etc., inthe compartments, it is important that'provision shall be made for affording access thereto in order that the compartments may be cleaned from time to LII time: To this end, I have provided each oi the outer compartments with an aperture 44, and each of these apertures is normally provided with a closure-device as, capable of readily being removed when desired. \Vhen occasion requires that sediment and other foreign matter that has deposited on the inside of the drum shall be removed,the separable halves 2 and 3 ot the casing are unlocked and disconnected, whereupon one or another, or all, of the closure devices may be removed, and then access to each of the outer compartments may be had- From the foregoing, itvrill be perceived that I have provided a simple, but none the less effective, structure .tor measuring and metering various kinds of fluids, such as water of condensation resulting from the use of the same as supplied from a central plant; furthermore, that this structure one which may readily be manufactured; and that, withal, precise results, as to the amount ot' steam consumed by a user, as determined by the amount of water or corn densation which results therelrom, can be ascertained at all times.
